I'm installing Xen Server 6.2 via PXE. I don't necessarily need/want it fully automated. All I'm after is a diskless install environment, which I have working. I'm able to boot Xen installation media from my PXE server and I've completed many successful installations. The main annoyance is that it asks for an install URL, which is long and I'm tired of typing it every time. I've tried creating an answer file with the URL I want, but unfortunately it seems to require fields such as time zone and primary install disk that I don't want to specify until the actual time of installation.

Maybe an answer file isn't the solution to my problem. Does anyone out there have good experience with Xen Server automated installations and answer files? Do you put up with having to type a source URL every time?
